Hi, everyone
I have generated an O grid mesh, which is showed in the following picture. When I checked the mesh quality, I found there were some overlapping elements. Who can help me eliminate the overlapping elements? thanks. 1.png overlapping elements.png |

That is my first try to mesh a 2d cylinder. And now i know why it looks so ugly: i have used "smooth mesh globally" function. Simon, can you help me about my current trouble :how to refine the mesh? I have described the problem: http://www.cfd-online.com/Forums/ans...mputation.html Generally speaking , i mean that i want to coarsen the mesh but the mesh should satisfy the following demand: 1. the first layer mesh should be close enough to the wall to make sure y plus approximate to one. 2. aspect ratio of mesh should not be big in order to be true of FLUENT's limitation. thanks very much. |

did you find a fix to these overlapping nodes? I'm having a similar problem where it just kinda goes up and folds over on its self..

Hey Ringtail are you all set on this... I can't tell much from your image. I don't even know if you have an Ogrid. I would need better images or the actual files to help any more on this one.
Best regards, Simon |
